Specifieation forming part of Letters' Patent No. 196,804, datcd November 6, 18'77 application filed i v October 18', 1871 ToalZ whom it may comem:

Be it known that I, Ronr', B. HUGUNIN, of the city, County, and State of New York, have in-vented certain new and useful mprovements in Sash-Holder's or Sash-Balances, of

1 the sash over its 'snrfaoe, from Vibration on its bearings. (See Fig. 1, detailed illnstrati'on.)

which the following is a specifioation;

First. Thisinvention consists in the application and use, in a sash-holder having a f using a roller and roller-arm, B, the bevele'd roller, of the aXle-holding proj'ections F F' ,1 the object being to fu'rnish instant support to the roller'through its axlles while holding the sash, after raising the same, preventing sagging, and causin'g the' weight of the sash, throughthe incline of F F' to oompress the roller against the rear br'ake G, enablin g F, F', and 'I G to resist the turning of the roller while holding and lowerin'g the sash. (See illustration in Fig. 1'.)

Second.` In eombining' with F', F', and Gthe front proj'ection G' 5. the object being additional support toV the/rolIer-surface while holding the sash, the bearings G G' and F F' being arrange'd with reference to each so as to fur; nisl`1 constant'bearings in their holding workuntil the roller' be so reduced in diameter as' tol be Worn ont. (See side ilhrstrationofsame in Fig- 1-) T ird'. The arrangement, combination, and use of a roller' snspended n'pon its holding or` clamping hearing` B, between the pin M and faceof the platel A, so that the weight of'the sash, held by fri'cton from the rolle11'',wil1proL duce a forwardthrow, or mechanical carnholding action onf the part of the' clainped roller between the hin-gelpin M and sash, r

against the sash, with the pin M, as` the main resisting' or piv'otal point the object being to obtain a positive or mechanical sash-holding power through the weight of the' sash, regn. lated-'to the weight of the saslr by' an adjusting-screw. (See Fig. 1.)z

Fourth. In combining with an adj ustingscrew, H, used for' sash-holder's, the coilg spring L,.arranged upon the neck of the screw' between the loose and secured washers and K; the object being to keepthearnr Band roller D: steadily pressing' against the sash,

the' extent of thev pressure: being limited by f car-Window,.sliowingthe* sash and chan;

more or less drawing of thel scr'ew E toward the sash in the adjustment, &c`. (See Fig; I.)'

Fifth. The anangerfientand combination:

` In a sash-holder using 'a roller and arm, B, the .lag-extensions S S' tend to steady and s1p p'ort the arm and roller, and to prevent the latter from sqnealing orwhistling in low'elingy Sixth. In combination with a sashfholder bearing's T, extending round the rim ofV the plate A the object being to obtain a close fit E in m'ortising the plate and working part-s into the jalnflb of the window. (See illustration, Elgin' Figure-1 is' anelevatifion plan with lu'g and plate broken away to showtheV features` and application of my invention, towit: The axleholding projections F'F', brake G, rest projecti'on S', in combination thercwtnth ar'- rangeinen-t of the roller and its bearingstocre'ate a mechanical holding action between the hinge-pi'n M and sash against the sash, fthe'- coi'le'd spring' L arranged upon the neck of the adjnsting-screw H between washers J and K; also, an illfnstration of the efficiency of the hearing-s F F' and G G' until the roller be completely redn'eed in diameter and worn ont also, i'llustration of the compression action of the roller under the weight of the sash by iiiclineof bearings F' F' againstthebrake G, and

an: illnstration of the lng-extension S and beyeled edges T extendi'ng round the plate A.

Fig. 3 is: an eleva'tion plan embracing features of l'n-yinvention adapted for carlwindows, Iwherc the screw-adiustment, from the sash:

working ip-Ward within an inclosed casing,

tales place froin the' side, through the Sashstop, (illustrated in Fig.` 5,) the slot-extension end B' being. then a projection from the side of the arm B1.

Fig; 'i's a section offthe: lfeft'h'and' j'amb of a Inel'sE and the stop between them, through' which the adjusting-screw H is reached, the hollow cavity for the screwzH in `the stopl bein g closed by a capped screw, R.

A is a face-plate, having a cavity for theadjustin g-screw H, and lugs N N' and lug-extensions S S'. B is the roller-arm, limited in its working by an adjusting-screw. B' is arear or neck proj ection of the roller-arm B. B is a balance-clamp bearing on the neck of arm B. B' is an upper or slot extension of arin B,

through and against which the screw I-I works 4 in regulating the pressure to the weight of the sash to be held for car-windows. (See Fig. 3.) C O' are inclined axle-bearings 011 the arm while raisingthe sash. A slight rockin g movement of clamp E in holding throws the rolleraxles from these bearngs. D is a metalbodied roller, covered with a semi-elastic rubber and fiber compound, supported upon its inner surface as a belt, with several thicknesses of thick or muslin cloth wound straight, not bias. E is the clamp, having aXle-bearings F F', brake G, and a bearing, G'.

F F' are aXle-holding projections, situated under and forward of the aXle-bearings O C' on the arm B, and forming with them a sort of slot for the roller-axles to work in. The funetions of F F' are to hold the roller by its axles and to act as fulcrum-rests, in connection with the brake G, to resist the turning of the roller under the weight of the sash. 'Their incline enables the weight of the sash to force the roller directly against the brake G, eifectually preventing it fromturning while holding or lowering the sash. G is a tangent brake projection, and, in connection with aXle-bearings' F F' to hold the roller from sagging with the sash, and to prevent it from turning while holding or lower-ing the same. G' is the frontroller-surface rest projection, used in connection with F, F' and G to give more solidity to the roller, and to prevent it from springing under the weight of the sash, and the latter from sagging therefrom. F F' and G G' are arranged, as shown in one of the illustrations in Fig. 1, to be eflicient in their work until the roller be so reduced in diameter as to be worn out.

H is an adjusting-screw used, in a connection with washers J and K and the coiled spring L, to regulate the pressure of the roller upon the sash, according to the weight of the sash to be held. I is a slot on arm B for the adjusting screw H to work through. J is a Washer secured on the rear end of the neck of the screw H for. confining spring L. K is a Washer playing loosely upon the neck of the screw H as a bearing to keep the lowerend of the spring L out of the slot I. L is a light coiled spring working upon the neck of the screw H. The functions of this spring are to keep the arm B with its confined roller pressing against the sash, according to the weight of the sash. This .pressure is regulated by the back and forward movement of the screw, of

'which it forms animportant part in this connection. M is a hinge-pin for hinging the arm B to the `lugs N N' of the plate A. In this mechanism the pin does most of the sash-holding work, directly. N N' are lugs running back from each side of the plate A, for securing the arm B. O is a stop between the sash and blind channels. (See Fig. 5.) P is a sashchan'nel car-window. Q is a blind-channel in a car-window. R is a hollow-capped screw, used to cover and protect the adjusting-screw, Fig. 5. S is an extension of lugs N N' for the purpose of steadying the roller D, through arm B, projections'F F', &c. This extension prevent-s the squeaking of the roller in lowerin g the sash. T is abeveled edge extending round plate A, enablin g a better fit in mortising the plate and the attached working' parts into the jamb of the window.

The mechanical holding power introduced in this mechanism in its various degrees is limited only by the stiffnessof the windowjambs and the strength of the metal. It is readily controlled to the weight of light and heavy sash in the same balance by the screw H, after the sashes and balances have been finally secured in their places.

If, after years of use, or from shrinkage of the wood-work, more holding power be required, it is instantly obtainable by further drawing the screws H, without removing the sashes or balances. I obtain all the holding power of a direct-acting cam or knuckle-joint Awith the use of the roller in raising the sash,

and the employment of its entire circumference as a wearing-surface. Without the use of the adj Listing-screw H, or its equivalent, this power could not be controlled, and hence made available for this purpose. By changing the position of the bearin g B on the arm B this power is readily modified so as to require a springpressure; in connection, to hold the sash. I i

use both the direct and spring pressure-one requiring parallel-edged sashes and stiffened jambs, and the other, the slight spring, renders this unnecessary. The adjusting-spring with the screw renders spring-pressure efficient for all medium windows.

VVhat I claim as my invention is- 1. The combination of the aXle-holding projections F F' upon clamp E withbrake G, substantially as and for the purposes specified.

2. In combination with projections F F' and brake G, the rest G', situated underneath, and between projections F F', substantially as and for the purposes specified.

3. The arrangement of the plate A and' arm B, having a rear-extended hinged neck, B', dropping perpendicularly to the bearing B, with roller suspended upon the bearing B", between the hinge-pin M and the face of the plate A, the weight of the sash carrying the same downward and outward onto the sash,

the proj ection of the roller being limited by the adjustin g-screw H to the Weight of the sash to the roller through the olamp E, and. proj eotions be held.7 substantially as and. for the purposes F F', substantially as and for the purposes speciged. b speoified..
